As pointed out, you need the Optispark. The signals are unique to it, so not the same as any other crank or cam trigger signal.

You could probably put a LT1 cam and front timing cover onto the engine, but it doesn't make much sense. Might as well do a 0411 PCM swap.

A 4X crank sensor and Vortec distributor with 1X sensor gives you a 0411 swap but I personally don't like that either because it still uses a single coil and the distributor for the ignition. In my opinion. a big advantage to doing a 0411 swap is getting the coil near plug ignition.
